Strong interactions preserve an approximate isospin symmetry between up (u) and down (d) quarks, part of the more general flavor symmetry. In case K meson production, if this were exact, it would result in equal numbers charged (K+ K−) neutral (K0 $${\overline{K}}^{0}$$ ) mesons produced collisions isospin-symmetric atomic nuclei. Here, we report results on relative abundance over production argon scandium nuclei at a center-of-mass energy 11.9 GeV per nucleon pair. We find that K+ K−...
Herein, we show that the substitution of Sr2+ by trivalent lanthanide ions (Lu3+, La3+, Tb3+) in SrTiO3 nanocrystals stabilizes and enhances Ti3+ near-infrared emission (around 800 nm). This occurs from 6-fold coordinated luminescent centers appear vacancy–Ti3+–O form after doping into site. The strong dependence on temperature provided means for tailored chemical engineering nanonthermometers able to read three ways: changes intensity, excited-state lifetime, ratio Tb3+ intensities. We...
The solution synthesis route as a scalable bottom-up synthetic method possesses significant advantages for synthesizing nanostructured bulk thermoelectric (TE) materials with improved performance. Tuning the composition of directly in solution, without needing any further processing, is important adjusting dominant carrier type. Here, we report very rapid (2 min) and high yield (>8 g/batch) using microwave-assisted heating, controlled growth Bi2–xSbxTe3 (x: 0–2) nanoplatelets. Resultant...

In this study, sol-gel derived Zn1-xMgxO (ZMO) is proposed as an electron transport layer (ETL) for solution-processed quantum-dot light-emitting diodes (QLEDs). It demonstrated that the increase of Mg content in films from 0% to 20% causes a dramatic suppression current, which attributed lifting conduction band minimum and reduction mobility. As result Mg-doping, charge carrier balance might be achieved QLED with Zn0.85Mg0.15O resulting maximum external quantum efficiency 5.74% current 18...
Scalable synthetic strategies for high-quality and reproducible thermoelectric (TE) materials is an essential step advancing the TE technology. We present here very rapid effective methods synthesis of nanostructured bismuth telluride with promising performance.
